I am on the rebuild part of my Cruiser 89 'Preservation'. The bike has been completely dismantled to the last bolt and, as it is too good to restore, is being rebuilt after cleaning/preserving and bits (seals/bushes) replaced where necessary/missing. To that end I am in need of the following (good used preferably or new if necessary):Green=now found.

1. Green front brake cable2. Green clutch cable3. Green throttle cable (4T-is it different to 2T?) - I used a Falcon 81 cable which has the same ends but is 1.5 inches longer.4. White faced wipac ammeter5. Air filter mesh/screen and outer circular cover (same as Falcon 87, (and Fulmar with removal of the mounting leg which is what I did)).6. Rear number plate and reflector.7. Headlight lens/reflector.8. Square finned rectifier and through bolt (the bolt was the only bolt to shear during the whole stripdown)..

Perhaps someone has discarded bits from their restoration which still have some life in them and could be put to further use. Please comment or PM me with your parts/prices.

Many thanks, Steve.

Strangely enough i have an air filter going on Ebay this evening ( ebay id piston197) but it is of a like i have never seen before, it consists of the angled box same as the 2T/4T Cruiser 89 round filter type, but it has the rectangular 4T sports cruiser 91 type filter box ??? any body seen one of these before ? it won't be on ebay until tonight about 8pm, but would welcome some comments JH

Air filter now on Ebay item No 401543204780 , have a look at this and tell me what you think ?? seems to be a Hybrid between the filter box used on a Cruiser 89 and the rectangular air filter used on other 4T twins ( Greeves, Enfiel Turbo Twin etc.?)Not got a clue what it originally came from, never seen one before ?JH

John,

I would have said that it is a home made job to enable a 4T to be fitted to a Cruiser 80; the alternative solution I have seen is a Cruiser 80 with the pressed steel rear frame cut away to enable a standard Villiers air cleaner to be fitted. The original FB Cruiser 89 air inlet was much better made and included a small bracket to enable one of the standard S25 air filter clips to be used to ensure a close fit to the carb. The original inlet was tapered in two dimensions - the example shown does not have the vertical taper. However, it might of course been an original fitting on a low volume bike manufactured other than by FB. Sandy

Definitely not home made, nicely spot welded etc and chromed as well, proper elements in the rectangular filter box as well, i have never seen this on any 250cc twin,so i cannot positively identify it, again if you were fitting a 2/4T engine into a Cruiser 80 could you not use the proper 89 filter,( assuming you had one ?)Still the jury is out on this one, it is on Ebay more in the hope of identifying it than anything else JH

Getting near to the end of the rebuild and wondered if anyone has any 4T downpipes with good flanges (cylinder end) that perhaps they replaced with new pipes and are sitting surplus on a shelf. Can be scruffy in appearance. Mine are scruffy as you can see in the pic above and if it wasn't for the corroded (to nothing) flanges I'd be reusing them.

Thank you Peter. If you do have some don't worry about cleaning them up. I like the authentic original look. I bought some silencers recently which have been ruined by the seller improving the look by removing rust with emery or maybe even a file. Chrome cleaner would have removed just as much rust and not damaged the chrome.

2T and 4T should be the same ? just one has an internal nut (4T) and one an external nut ( 2T) but the pipes and flanges should be the same ?? Maybe just a little difference in the length at the top as the 4T ones go into the cylinders by about an 1" and the 2|T ones are outside by about1"JH

Bigjim, I have zero knowledge of electrics but as I understand it the 4T has full wave rectification and as such has two AC connections from the magneto. The central bolt is the earth and there are two other wires from the headlight switch. As I understand it the modern rectifiers available have only one AC connection and are therefore half wave?

Yes you partly correct. The older 2T used flywheel magneto coil ignition. The 4T used more modern battery coil ignition. A modern bridge rectifier has 2 AC inputs, it doesn't matter which goes where and 2 DC outputs. Plus & minus. They do matter. Yes it is full wave. When I get home I'll look up my Wipac book for a wiring diagram.
